摘要
矿带主要赋存于板溪群五强溪组上段之韧性剪切断裂带内,由近80条规模不等、含金性不一的锑金石英脉组成。金的富集与金属硫(砷)化物关系密切,毒砂是其主要载金矿物。褪色带内硅化、毒砂化是近矿围岩标志,砷是其标型元素。
The Longwangjiang mineralized zone consists of about 80 antimony-gold quartz veins,hosted in ductile shear zone within the upper part of Wuqianxi Formation. Banxi Group. The quartz veins are various in dimension, and different in gold content.The gold enrichment is closely connected with metal sulfide(or arsenide). and arsenopyrite is the main gold-bearing mineral. The silisification and arsenopyritization within the decolored zone are the indicators for near-ore wall rocks, and arsenic is their typomorphic element.
